WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 299,257, dated May 27, 1884:.

Application filed December 19, 1883. (No model.)

To (2% whom it may concern.-

Be it known that I, S. EUGENE Pnnnrsn, of Lowell, in the county of Kent and State of Michigan, have invented new and useful Improvements in Adjustable XVindow-Screens; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to certain new and useful improvements in the construction of adjustable window-screens, which improvements render the screen more perfect in its operations, more easily adjusted, and less liable to get out of order than those constructed in the usual ways.

The invention consists in the peculiar combinations and the construction and arrange ment of parts, as ,hereinafter more fully described and claimed.

Figure l is an elevation of my improved screen in position in a window-frame. Fig. 2 is a vertical section through the top frame on the line y 3 of Fig. 1. Fig. 3 is a cross-section of the device 011 theline z z, same figure. Fig. 4 is a perspective detail.

In the accompanying drawings, which form a part of this specification, A A represent two rectangular frames of equal size, or nearly so, which hold the wire-cloth screen B in place. The inner and adjacent faces of each of these screen-frames are fiat, while their exposed or outer faces are beveled and in the form of moldings. To the rear face of the frame A and top and bottom rails, and the wholelength of such rails between the sides of the frame, is secured the doubled recessed female slide a, formed of thin sheet metal, substantially of the form shown in Fig. 2, with the backwardlyprojecting flange let in and secured in a sawkerf in said top and bottom, so that said slides run longitudinally parallel to each other. Upon the adjacent face, and similarly situated and similarly secured to the frame A, is the double-tongued male slide Z), so that when these two slides engage the two frames are secured together by means of a continuous bearingslide, so that the two parts of the frame may be closed upon each other or extended at will. The corners of these frames of the- A A are not mitered, but are secured solidly together at such corners by mortise and tenon, as shown in Fig. 4; and in putting the frame together and securing the screen therein the top and bottom rails on their inner edges have asaw-kerf into which the wire-cloth is drawn. Then one of the sides of the frame is fitted in place, and, the wire-cloth projecting onto it, a stop, 0, consisting of a thin piece of wood, is nailed onto the rear side of this side of the frame, by means of which the screen is secured to that side, and then the other side of the frame is put on in the same way, the stops on the inner edges of the sides being thicker than those upon the outer sides, so that there will be a bearing against the face of the cloth as the screen is extended, to the exclusion of insects, and these stops also prevent the parts being disengaged in adjusting the screen to the window. Projecting from the top and bottom rails of the frame A are spurs d, designed to secure the slide a in position, and,when the frame is in place in the window-frame'and the sash drawn down fipon it, to engage with the bottom of the frame and the bottom of the sash, thereby holding this frame A rigidly in position and leaving the other frame, A, free to be adjusted, as may be desired, to close or disclose any portion of the window-opening. The frames A and A are made, preferably, of square pieces of timber, and, after being secured together, as described, at the corners, are run through a sticker or other suitable mechanism, by means of which an ornamental bevel is given to the outer faces; and this is found important, for the lower rail of windows is usually made beveling upon its bottom edge, and this formation of the screen-frames prevents, when the sash is drawn down upon the frame, any opening being left through which insects might crawl, which occurs in the use of most of the adjustable frames now in the market. a

I make no claim to the use with my screen of the sharp points used to engage with the sash or sill, as I am aware that such points are not new in this connection.

What I claim as my invention is 1. An adjustable screen-frame consisting of two rectangular frames secured to each other,

back to back ,by means of metallic female slides attached to one and double-tongued metallic male slides attached to the other, whereby a continuous bearing is obtained in adjusting the relative position of such two parts of the frame, substantially as described.

2. An adjustable screen-frame consisting of two rectangular frames secured to each other, back to back,by means of metallic female slides secured in a saw-kerf in one and double- 1o tongued metallic slides secured in a saw-kerf in the other, substantially as and for the purpose specified.
